Regal Jumping Spider

Quick Overview

Size: ⅕-⅘”

Characteristics:

The regal jumping spider is about the size of a dime when measured with its legs outstretched. It has large, distinctive eyes, a flat-faced appearance, and is best characterized by its quick, jerky movements. 

Habitat 

Regal jumping spiders can be found in open woodland and field habitats. They often wander indoors where they are frequently found on the walls of buildings. 

Behavior 

These spiders use their superb vision to find and catch prey (as well as to detect mates). They catch their prey by jumping on it. 

What does a regal jumping spider look like?

These spiders, like most jumping spiders, are small. They generally only reach around half an inch or so in length. Males are always black, with alternating white and black fringes on their legs. 

Females are larger than males with the same color pattern as males. However, they also have black dorsal areas that are covered with colorful scales. In Florida, most females have bright orange scales, though this can vary. Females also have four tufts of setae near their eyes, while males do not. 

Most importantly, jumping spiders can be identified by their unique eye arrangement. They are arranged in three rows, with the fist containing four eyes, the second containing two tiny eyes, and the third row also containing two small eyes. The regal jumping spider is the largest and hairiest in the area.

Regal Jumping Spider Facts and Myths

1. Fact: Regal Jumping Spiders Don’t Use Webs

Regal jumping spiders don’t make webs to capture their prey. However, they do use silk. They trail a dragline behind them to break their fall if they happen to miss a jump and females use their silk to build nests for laying their eggs. 

Other than that, regal jumping spiders hunt their prey instead of capturing it in webs.

2. Fact: Regal Jumping Spiders Can Be Trained to Do Tricks

Although it’s not recommended that you try to hold one of these spiders in your hand – they can bite when held too tightly – these spiders are some of the easiest to tame. In fact, many people have been able to train them to jump back and forth between their hands.

3. Myth: Regal Jumping Spiders Are as Dangerous as Black Widows

This is a myth. Regal jumping spiders can bite, but it’s not a toxic bite. They are frequently confused with black widow spiders because they are large and black. However, black widows are not hairy at all and have longer, more spindly legs. Regal jumping spiders are harmless while black widow spiders can be quite dangerous.

4: Fact: Regal Jumping Spiders Eat Other Spiders

These opportunistic eaters will consume just about anything including other arthropods and even other spiders. 

5. Fact: Regal Jumping Spiders Have Great Eyesight

…and with all the eyes they have, they really should have great eyesight, don’t you think? It is the spider’s four oversized eyes that help give them the best eyesight imaginable. While these small eyes provide a wide-angle view and help with motion, the larger eyes give them a detailed view of the world in color.
